I have a AKAI projection TV. It is about 6-7 yrs old. The picture seems to be slipping down with a rainbox line at the top. Something is going out like the old days when a "picture tube" went...


Hi Scott,
Your convergence board gone bad. You may replace the Chip and other resistor around or buy online with the board replacement. If you want to do it yourself try the availability of the board on ebay.com or shopjimmy.com.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

AKAI PROJECTION TV 54" - 6 YEARS OLD, DULL PICTURE


PLEASE BE CAREFUL WHEN DOING THIS PROCESS!!! YOU WILL DESTROY YOUR CIRCUIT BOARD LIKE I DID IF YOU DO NOT TAKE YOUR TIME OR ARE CAREFUL!!
What you need to do is clean the CRT coolant inside the TV. Here is a forum that I SHOULD have read before doing mine:

CRT COOLANT REPLACEMENT AND CLEANING

I was lazy and not taking my time to take care in not dripping any CRT coolant and some got on my circuit board, ( I felt confident since I had changed the Blue CRT 2 years prior) and I was only able to see about 1 hour of the best viewing my TV has ever given me since it was new, it looked like a miracle had happened. My TV was "dull" as the best way to describe it, colors faded, kinda fuzzy. I briefly researched into it again to refresh my memory then jumpted right into not really taking any precautions. I got lazy and didn't take out the CRT's like I did the first time with the Blue CRT and paid the price for it. Let me tell you, theirs nothing worse than getting a perfect brand new like picture only to loose it and hour later because of carelessness. Take out the CRT's, take your time, label everything and take pics, the reward is WELL worth it. Oh ya, you can use Mineral oil instead of the coolant that they sell at stores. Its not conductive, and dose'nt damage the circuit board if u spill a little. I used Baby Oil the first time I did it and when I went back to change the green CRT this time around it was still crystal clear, no discoloration in the Blue CRT I had done 2 years prior. I hope your results come out better than mine did!!

Color!


the dull and faded color could mean you need to change the coolant.
you could also try and adjust your convergence.

Picture fading


YES, THE CRTS WILL START SHOWING THEIR SIGNS OF WEAR. TO REPLACE THEM IS MORE THAN YOU PAID FOR THE SET.

Red and Yellow blurred picture


I had the same problem this week. I tried the convergence thing but it was impossible to fix. I still needed the repairman. He changed two convergence units ($325, parts and labor). Then the tv was still doing the same thing. We had to adjust the convergence and now everything is perfect. You will need your converter
